US LNG Exports Projected to Double, Attracting $1 Trillion in Infrastructure Investment by 2040

The U.S. liquefied natural gas (LNG) industry is projected to attract more than $1 trillion in supply chain investment by 2040, driven by a massive expansion in export capacity over the next five years. Following the lifting of a federal pause on new export approvals, a wave of final investment decisions has accelerated the buildout of Gulf Coast terminals and associated infrastructure.[1][6]

A comprehensive analysis by S&P Global Energy forecasts that U.S. feedgas demand for LNG exports will double to 36 billion cubic feet per day by 2031. This surge in capacity is expected to elevate LNG to the nation's second-largest net export industry, trailing only civilian aircraft and aerospace parts.[1][3]

The economic multiplier effect of this expansion is expected to be unprecedented. Through 2040, the industry is projected to contribute $1.4 trillion cumulatively to the U.S. gross domestic product. The $1 trillion in capital expenditures will generate an estimated $2.9 trillion in business revenues, $206 billion in federal and state tax receipts, and nearly $630 billion in labor income.[2][6]

Crucially, the financial windfall will not be isolated to traditional energy hubs like Texas and Louisiana. The analysis indicates that 42 percent of the supported jobs and 33 percent of the GDP contributions will occur in non-gas-producing states, driven by nationwide demand for steel, engineering services, and manufacturing components. In total, the sector is expected to support 550,000 jobs annually.[1][6]

Despite the massive volume of gas leaving the country, the impact on domestic utility bills is projected to remain minimal. The study estimates that average household natural gas costs will rise by just 1.6 percent between 2026 and 2031. The U.S. currently produces gas at a rate that has historically outpaced export growth by a factor of three, keeping the broader domestic market well-supplied.[2][4]

However, regional price stability depends entirely on the construction of new midstream infrastructure. Industry advocates note that localized price spikes are driven by pipeline bottlenecks rather than a lack of underlying supply. Expanding pipeline capacity into constrained markets like the U.S. Northeast could actually reduce peak winter gas prices by more than 20 percent over the next five years.[3][4]

On the global stage, the investment wave is poised to cement American energy dominance. The U.S., which became the first country to export over 100 million metric tons of LNG in a single year in 2025, is expected to capture roughly one-third of the global market by the early 2030s. This market share provides significant leverage in international trade and energy security negotiations.[2][5]

The geopolitical stakes of maintaining this growth trajectory are high. If the projected export capacity fails to materialize—whether due to regulatory hurdles or capital constraints—global LNG markets would tighten severely. Analysts warn that such a shortfall could drive natural gas prices in Europe and Asia up by 50 percent, effectively transferring billions of dollars in revenue to rival energy suppliers.[1][7]

With global energy demand continuing to rise alongside the electrification of the economy and the proliferation of data centers, the U.S. LNG sector is positioning itself as the primary baseload provider for allied nations. As new terminals come online, the focus will shift to securing the upstream production and midstream pipelines necessary to feed the trillion-dollar export machine.[5][7]
